Compressed air pipe sizing calculation

Here's an example calculation using the compressed air pipe sizing table (table 1) and the equivalent pipe length table (table 2) Let's say we have a rotary screw compressor of 30 kW that can supply 250 Nm3/hour (normal cubic meters per hour) 250 Nm3/hour is the same as 4200 Nl/min (normal liter per minute) or 150 scfpm (standard cubic feet per minute) Get price

How To Design Bag Filters • FGKH

L bag 6m = 20ft To calculate your tube sheet surface required for your filtering area calculate at least 200 mm of "bag to wall" clearance (referred to bag centreline) and at least 220 mm of "bag to bag" clearance Now that you learnt how to design bag filters go to Bag Filter Design Calculator to start designing your bag filter!Get price



The maximum allowable filter velocity is 300 feet per minute (fpm) on disposable filters The above example would yield 360 fpm and a disposable filter could not be used For best results use 2 00 cubic feet per minute per square inch of filter area Example 2 2000 200 inches = 1000 square inches of 40 X 24 filter Get price
